These nuts take pretty much forever to eat (the cracking! the shells!), which, while annoying, is great for your metabolism. Having small meals and snacks, like pistachios, throughout the day allows your body to process them more efficiently.

This fruit has a super-high water content, so much like veggie soup, it helps keep your system running smoothly to ensure that your metabolism is working at its best. Plus, thanks to their high fiber content, blueberries keep you regular.

Mandarin oranges

Studies have proven that the smell of citrus calms you down and reduces levels of cortisol, the body’s stress hormone. And when you’re not bugging out, you’re less likely to reach for sugary comfort foods, which throw your metabolism out of whack. Other citrus fruits, like grapefruit, also do the job.

Kale

Even more reason to grab a green juice after your workout: The leafy green contains lots of protein and fiber, both of which keep you full without spiking your blood sugar, which could mess with your metabolism. Other green veggies—think spinach and Brussels sprouts—are great too.

Hemp seeds

You don’t have to be a Grateful Dead fan to get on board with these seeds. They’re a great source of omega-3 and omega-6 fatty acids, both of which improve blood flow to your muscles, revving up your metabolism. Plus, they reduce inflammation.

Matcha

Yup, that’s just a fancy word for green tea. It not only packs a bit of caffeine, which speeds up your heart rate and thus your metabolism, but it also has norepinephrine-stimulating EGCG, a nutrient that helps boost your metabolic rate.

The go-to snack is packed with protein, which takes longer to digest than carbs or fiber. And when your body has to work harder to break down a food, it burns more calories, supercharging your metabolism.
